    During electron bombrament within mass spectrometer, there will be a peak recorded at m/e ratio at 89 if one of the methyl groups is clevaged at either 3rd or 4th position of carbon skeleton. Anyway, electron bombarment with the above-mentioned compound will give several possibility.

    Precsiely, you should read the peak from the mass spectrum of 3.4-dimethylhexane but not predicted in theory.

    Hope this help!
